OUR COMPANY'S CFG SERIES DRILLING MACHINE HAS THE FEATURES AS BELOW: 1 The drill machine used the long screw to dig the hole and can perfuse concrete into the holes bottom through the center of drill rod. It can make pile only by one machine in one time, as well as suitable for dry method, replacement of infuse and some other construction processes. 2 The rotary head device adopted speed reducer with large hole through the center and drove by double-motor, which guaranteed the high bearing capacity, compact structure, low noise and long service life. Its the most idealest power device in domestic pile drive field at this present. 3 Hydraulic static moving device is adopted for this pile-driving frame, so that it can raise and down the arm frame automatically, walk, rotary and accurate emplacement and reliably, as well as high efficiency and low strength of labor. 4 Drill rig adopts the combined way of consignment and shipment, features good integrity, easy to transfer and low expense cost. 5 All the monitoring instruments which for electric, hydraulic, operation are centralized at the driver cab. Its convenient and easy to operate.
